INSPECT EGR VALVE POSITION SENSOR
Inspect the resistance of the EGR valve position sensor.
(1) Disconnect the EGR valve position sensor connec-
tor.
(2) Using an ohmmeter, measure the resistance be-
tween the terminals VC and E2.
Resistance: 1.5 – 4.3 kΩ
(3) Reconnect the EGR valve position sensor connec-
tor.
Inspect the power output voltage of the EGR valve posi-
tion sensor.
(1) Disconnect the vacuum hose from the EGR valve.
(2) Turn the ignition switch ON.
(3) Connect a voltmeter to terminals VC and E2 of the
ECM, and measure the power source voltage.
Voltage: 4.5 – 5.5 V
